Which in itself is a problem: it means the MFA device is not required, if only they have access to my email + phone.

Sure, I know. Just pointing out that, at least for AWS, you do not need recovery codes or a second device for MFA. For me personally, phone+email is good enough for my threat model.

Yes, AWS MFA is very poorly implemented.
